Trip Purpose General site visit, install RRR & automate data acquisition/file renaming on 2 data loggers

Tonzi Ranch:

29Nov06
Install Radiobot Radiation Railroad and log raw 1Hz data.

Attach RS232 cable to Snyders surface renewal data logger and attempt to communicate with logger. Failure. 100 foot RS232 cable has discontinuity in 2 of 10 conductors. Cut cable in half and continuity failure resides only on one half. Use one with continuity by soldering on 9 pin Sub D connector and cable now functions. However, the Usb-RS232 adapter I brought does not function.

30Nov06

Reconnect 2 auxiliary solar panels into floor power system

Automate data acquisition from SapFlow logger but again RS232 – USB adapter failure. This logger is named CR10X12.

This logger is showing many –6999 indicating open circuits on several channels.
